The effect of various level of skipjack tuna bone meal (Katsuwonus pelamis L.) in ration on broiler carcass tenderness and abdominal fat

Hundred day old chicks Arbor Acres CP-707 were used randomizedly in this experiment, to study the effects of various levels skipjack tuna bone meal in ration on broiler carcass tenderness and abdominal fat, and were studied for six weeks. Research using Completely Randomized Design (CRD). The dietary treatments are: R0 basal diet as control, R1 basal diet + 2% tuna bone meal, R2 basal diet + 4% tuna bone meal and R3 basal diet + 6% tuna bone meal, and each treatments were repeated five times. Results indicated that the highest carcass tenderness was get from the broiler that fed basal diet with 6% tuna bone meal (125,4 mm/g/10sec) and the lowest was get from the broiler that fed basal diet (107 mm/g/10sec). For the abdominal fat, the results is broiler that adding skipjack tuna bone meal in the ration will give more abdominal fat to the broiler (1.89% - 1.92%) versus 1.85% for basal diet.
